关于“克分子”的讲解,一般是这样的顺序,先说明“克分子是用克做单位来表示的物质的一定的量,在数值上等于它的分子量”然后再证明“各种物质一克分子里含同数的分子”,这个讲解顺序,是很多同志采用着的,教科书上也是这样。我却采取了另外的讲解顺序,或者叫相反的路线,我首先向学生说明的是:所谓“克分子”,就是“6.023×10~(23)个分子”,一个克分子的水就是6.023×10~(23)个水分子,一克分子可以说是6.023×10~(23)个分子的简称,然后指出:一克分子某物质的重量,正好等于该物质分子量的克数。我认为,从教学法的角度来看,我采取的讲解路线更优越些,主要理由有二:1.教员讲课,必须把主要的本质的教给学生,一克分子的任何物质,重量各不相同,然而,它们都含有 The explanation of “molecule” is generally the order in which “the molecule is a certain amount of substance expressed in grams, numerically equal to its molecular weight,” and then it is proved that “one gram of each substance Molecules containing the same number of molecules, ”the order of explanation is adopted by many comrades, textbooks as well. I have taken another explanation of the order, or called the opposite route, I first explain to students is: the so-called “mole” is “6.023 × 10 ~ (23) molecules”, one mole of water is 6.023 × 10 ~ (23) water molecules, one gram of molecules can be said to be 6.023 × 10 ~ (23) molecules referred to, and then pointed out: one gram of a material weight, exactly equal to the molecular weight of the material grams. I think that from a pedagogical point of view, I have taken a more advantageous course of explanation for two main reasons: 1. The instructor must give lessons to the students, Same, however, they all contain
